Catering representatives on Tuesday said restaurants will struggle with increased operating costs under an upcoming ban on plastic tableware.

Under the first phase beginning April 22, restaurants will be banned from selling and using disposable polystyrene tableware, plastic straws, stirrers, cutlery and plates.

Simon Wong, head of the Federation of Restaurants and Related Trades, said the ban will be a burden on small businesses.

"Don't underestimate the cost of a straw, a fork, or a spoon. Even if it's just ten to twenty cents, when you add up all the expenses, it can increase monthly spending to a certain extent. This additional cost can put pressure on small business owners," he said.

Echoing his views, a restaurant owner surnamed Yeung said he finds it difficult to find affordable alternatives.

"The average price of styrofoam is around HK$1. But the designated recyclable materials cost around HK$3 to HK$4. The socio-economic environment is not good. If we pass on the cost to consumers, they won't be able to afford it. This will result in reduced sales and make our business very difficult," he said.

Meanwhile, Executive Councillor Lam Ching-choi said he sees no reason to postpone the ban.

He told Ming Pao that non-plastic substitutes are just 10 to 20 cents more expensive, so most customers should be able to adapt to the changes in late April "without pain".

Complimentary amenities in hotels and hostels are also to become a thing of the past starting on April 22, but the head of the Tourism Association Timothy Chui said it may affect the SAR's image if tourists unfamiliar with the policy are charged.

"In some famous hotels, they beautifully package and offer sanitary products for guests to take as souvenirs. This is part of their brand's publicity and image," he said.

"Not many tourists are interested in learning about local environmental policies. So, if a guest happens to not bring these products, they will be charged. Will it make them feel like Hong Kong or our hotels are stingy?"

The Environmental Protection Department said it has organised seminars and other activities to help retailers gain a better understanding of the policy.
